“The cooperation with Honda has been running very well with Toro Rosso so far,” added Marko, in reference to Red Bull's junior team, who switched to Honda engines this season.

“After the McLaren disaster, Honda was close to a departure from Formula 1 at the end of 2017 and we really had to convince the Japanese in intensive conversations that they could resume with us to start.”

Red Bull will have a new driver lineup for 2019, with Australia’s Daniel Ricciardo already confirming he’s leaving the team to join Renault, with Frenchman Pierre Gasly taking his place alongside Max Verstappen.

The latest comments are far from the first time Marko has threatened that Red Bull will quit the sport. The controversial Austrian is rarely far from the headlines, often suggesting team owner Dietrich Mateschitz will walk away from his investment in the sport if he doesn’t get his way.

Red Bull has struggled since the switch to hybrid engines in 2014, finding themselves consistently behind Mercedes and Ferrari in the battle for race wins. The team is currently third in the championship ahead of next week’s Singapore Grand Prix.
